Description
Plane is an open-source project management tool. Prior to 1.4.0, BulkEstimatePointEndpoint.destroy resolves an estimate point through a bare primary-key lookup without workspace, project, or estimate scoping. An administrator or member of one workspace can permanently delete an estimate point belonging to another workspace by supplying the target UUID in a URL under the attacker's own workspace. This creates a destructive cross-tenant IDOR. This issue is fixed in 1.4.0.
